[0028] Combine Figures 1 to 4 As shown in the figure, the XYZ coordinate axes are used to provide a reference for the orientation description of related components in the following text, wherein the positive direction of the Z axis represents the top direction of the vehicle (i.e., above), the negative direction of the Z axis represents the bottom direction of the vehicle (i.e., below), the positive direction of the Y axis represents the left direction of the vehicle (i.e., left), the negative direction of the Y axis represents the right direction of the vehicle (i.e., right), the positive direction of the X axis represents the front direction of the vehicle (i.e., front), and the negative direction of the X axis represents the rear direction of the vehicle (i.e., rear).

[0029] The utility model provides a seat pivot bracket, including a bracket 1 and a cover plate 2, the bracket 1 including a bracket main plate 11, a bracket bottom plate 12, and a bracket top plate 13, the cover plate 2 is detachably connected to the bracket top plate 13, the bracket top plate 13 is integrally connected to the bracket main plate 11, the bracket bottom plate 12 is integrally connected to the bracket main plate 11, and the bracket bottom plate 12 extends in the left and right directions to protrude from the bracket main plate 11.

[0030] Combine Figure 1As shown, the seat cross beam 100 is generally arranged along the Y-axis direction in the figure, and the bracket base plate 12 can be installed on the seat cross beam 100 by bolt connection, welding, clamping and other connection methods. The bracket main plate 11 is generally parallel to the ZX plane in the figure, and plays a role in supporting and transmitting force for the bracket top plate 13. The cover plate 2 is detachably connected to the bracket top plate 13, so that the seat shaft 200 can be installed at the bracket top plate 13, limited by the cover plate 2 and the bracket top plate 13, and can rotate relative to each other, thereby realizing the function of folding down or lifting the seat back. In this embodiment, the bracket top plate 13 is integrally connected to the upper part of the bracket main board 11 (i.e., the positive side of the bracket main board 11 along the Z-axis), and the bracket bottom plate 12 is integrally connected to the lower part of the bracket main board 11 (i.e., the negative side of the bracket main board 11 along the Z-axis). The entire bracket 1 can be made of cast aluminum, thereby realizing the integrated connection of the bracket main board 11, the bracket bottom plate 12 and the bracket top plate 13, and the aluminum bracket 1 is also conducive to the overall weight control of the seat shaft bracket, ensuring that the overall weight is as small as possible while the integrated design is adopted.

[0031] For example, the cover plate 2 and the bracket top plate 13 are detachably connected by a connection method such as bolt connection, clamping, plugging, etc., so that the seat shaft 200 can be installed between the cover plate 2 and the bracket top plate 13, and the cover plate 2 can also be removed to remove the seat shaft 200. The specific detachable connection method is not limited here; Figure 2 As shown, the bracket base plate 12 extends in the positive and negative directions of the Y-axis in the figure, respectively. In this way, compared with the two side walls of the bracket main board 11 facing the positive and negative directions of the Y-axis, the bracket base plate 12 protrudes a certain length. When viewed in the negative direction along the X-axis, the bracket main board 11 and the bracket base plate 12 form a structure similar to an inverted T-shape. The specific protruding length of the bracket base plate 12 is not limited here, and the two protruding parts facing the positive and negative directions of the Y-axis in the figure can be asymmetric or symmetric, and can be adaptively designed according to factors such as actual seat layout requirements.

[0032] In the seat pivot bracket of the present invention, the bracket main board 11 of the bracket 1 is integrally connected with the bracket top plate 13 of the bracket 1, and the bracket main board 11 is integrally connected with the bracket bottom plate 12 of the bracket 1, so that the bracket bottom plate 12 protrudes from the bracket main board 11, and the cover plate 2 is detachably connected to the bracket top plate 13, so as to realize the function of connecting the seat cross beam 100 with the seat pivot 200 through the seat pivot bracket. The integrated design greatly reduces the number of parts of the seat pivot bracket, integrates multiple parts in the traditional technology into one to form the bracket 1, and improves the seat pivot bracket. The degree of integration is conducive to improving production efficiency; and the reduction in the number of parts reduces the weight of the seat pivot bracket to a certain extent, which is conducive to controlling the weight of the car; after the bracket base plate 12 and the seat cross beam 100 are installed, the bracket base plate 12 supports and transmits force to the bracket main plate 11 and the bracket top plate 13, and the part of the bracket base plate 12 protruding from the bracket main plate 11 plays a stabilizing and reinforcing role, and provides relatively stable and reliable support for the seat pivot 200 through the seat cross beam 100 and the seat pivot bracket, thereby improving the user experience when the seat back is folded down or raised.

[0033] Furthermore, it also includes a first rib 3, which is arranged between the bracket main board 11 and the bracket bottom board 12, and is arranged corresponding to the rear edge of the bracket main board 11 and the rear edge of the bracket bottom board 12.

[0034] Combine Figure 1 and Figure 2 As shown, more preferably, the first rib 3 adopts a triangular rib structure, and a first rib 3 is provided on both sides of the bracket main board 11 along the positive and negative directions of the Y-axis (the plate surface of the first rib 3 is substantially parallel to the ZY plane in the figure), and the position of the first rib 3 corresponds to the rear edge of the bracket main board 11 and the rear edge of the bracket bottom plate 12. The first rib 3 and the bracket 1 can both be made of cast aluminum and are integrally connected by casting.

[0035] In this way, by setting the first rib 3 between the bracket main board 11 and the bracket bottom plate 12, the bracket 1 is strengthened and reinforced to avoid breakage at the connection between the bracket main board 11 and the bracket bottom plate 12; at the same time, the first rib 3 is correspondingly set at the rear edge of the bracket main board 11 and the rear edge of the bracket bottom plate 12, which can also play a certain avoidance role and avoid interference with surrounding components.

[0036] Furthermore, it also includes a second rib 4, which is arranged at the edge of the bracket main board 11 and extends in the left and right directions to protrude from the bracket main board 11. The second rib 4 is connected to the bracket bottom plate 12 and forms a hollow groove 40 with a closed boundary.

[0037] Combine Figure 2 and Figure 3 As shown, exemplarily, the second rib 4 is a strip rib structure, and the second rib 4 is arranged along the edge of the bracket main board 11 and extends toward the positive and negative directions of the Y-axis in the figure. Compared with the plate surface on both sides of the bracket main board 11 facing the positive and negative directions of the Y-axis, the second rib 4 protrudes by a certain length (the specific protruding length of the second rib 4 is not limited here, and the two protruding parts facing the positive and negative directions of the Y-axis in the figure can be asymmetrical or symmetrical, and can be adaptively designed according to actual needs), the bracket base plate 12 is connected to the second rib 4, and a hollow groove 40 is formed on the left and right sides of the bracket main board 11. The hollow groove 40 has a closed boundary, that is, the figure formed by its frame (that is, the second rib 4 and the bracket base plate 12) is a closed figure. Figure 2 and Figure 3 The hollow groove 40 on the right side is shown, that is, the hollow groove 40 on the opposite side of the Y axis, and is Figure 3 The dotted line in the figure exemplarily shows the closed boundary formed by the frame of the hollow groove 40; Figure 2 and Figure 3 Due to viewing angle limitations, the left hollow groove 40, i.e., the hollow groove 40 on the positive Y-axis side, is not shown. It is conceivable that a second rib 4 of the same shape or a second rib 4 of a different shape could be provided on the left side. This design can be adapted to actual needs. Furthermore, the second rib 4 and the bracket 1 can be made entirely of cast aluminum to achieve an integral connection through a casting process.

[0038] In this way, the second rib 4 is set on the edge of the bracket main board 11 and extends and protrudes to the left and right directions, so that the second rib 4 is connected to the bracket bottom plate 12 to form a hollow groove 40. The frame of the hollow groove 40 (that is, the second rib 4 and the bracket bottom plate 12) plays a role in strengthening and reinforcing the left and right sides of the bracket main board 11.

[0039] Furthermore, at least one cylindrical rib 401 is provided in the hollow groove 40 , and corresponding to each cylindrical rib 401 , at least two strip ribs 402 are provided around it, and the strip ribs 402 extend radially until they are connected to the second rib plate 4 and / or the bracket base plate 12 .

[0040] Combine Figure 2 and Figure 3 As shown, two cylindrical ribs 401 are provided in the hollow groove 40, one of which is close to the positive direction of the Z axis, and the other is close to the negative direction of the Z axis. Six strip ribs 402 are provided around each cylindrical rib 401. The six strip ribs 402 extend radially around the cylindrical rib 401 (i.e., multiple strip ribs 402 start from one cylindrical rib 401 and extend in a direction away from the cylindrical rib 401). The angles between adjacent strip ribs 402 can be equal or unequal. Figure 3As shown, the cylindrical rib 401 near the positive direction of the Z axis has its strip ribs 402 extending radially to connect with the second rib plate 4; the cylindrical rib 401 near the negative direction of the Z axis has one strip rib 402 extending in the positive direction of the Z axis and slightly in the negative direction of the X axis to connect with the second rib plate 4, one extending in the positive direction of the Z axis and slightly in the positive direction of the X axis to connect with the second rib plate 4, one extending in the negative direction of the Z axis and slightly in the positive direction of the X axis to connect with the bracket base plate 12, one extending in the negative direction of the Z axis and slightly in the negative direction of the X axis to connect with both the second rib plate 4 and the bracket base plate 12, and one extending in the negative direction of the Z axis and slightly in the positive direction of the X axis to connect with the second rib plate 4. It is understandable that for a single strip rib 402, it can be connected to the second rib plate 4, the bracket base plate 12, or simultaneously connected to the second rib plate 4 and the bracket base plate 12 (i.e., connected to the junction of the second rib plate 4 and the bracket base plate 12).

[0041] In this way, a grid surrounded by multiple reinforcing ribs is formed in the hollow groove 40 by the cylindrical ribs 401 and the radial strip ribs 402, so that the force can be transmitted along the strip ribs 402, the cylindrical ribs 401, and the second rib plate 4, thereby strengthening and reinforcing the bracket base plate 12 and the bracket main plate 11. At the same time, due to its hollow grid design, it ensures that the weight of the bracket 1 will not increase too much, which is beneficial to the weight control of the car.

[0042] In particular, when two or more cylindrical ribs 401 are provided in the hollow groove 40 , for two adjacent cylindrical ribs 401 , at least one strip rib 402 on one cylindrical rib 401 is integrally connected with at least one strip rib 402 on the other cylindrical rib 401 .

[0043] Combine Figure 3 As shown, through the strip ribs 402, the cylindrical rib 401 close to the positive direction of the Z axis is connected to a strip rib 402 extending in the opposite direction of the Z axis, and the cylindrical rib 401 close to the opposite direction of the Z axis is connected to a strip rib 402 extending in the positive direction of the Z axis. The two strip ribs 402 are connected as one, thereby playing a certain role in strengthening and reinforcing the two cylindrical ribs 401.

[0044] Furthermore, the second rib 4 includes a front rib 41, an upper rib 42 and a rear rib 43 that are connected to each other. The middle part of the front rib 41 is recessed toward the rear to form a C-shaped structure, and the rear rib 43 is arranged perpendicular to the upper side wall of the seat beam 100.

[0045] Combine Figures 1 to 3As shown, the second rib plate 4 is composed of a front rib plate 41, an upper rib plate 42 and a rear rib plate 43, wherein the upper rib plate 42 is located at the edge of the positive side of the bracket main board 11 in the Z-axis direction, and it can be designed according to the specific shape of the edge of the bracket main board 11 along the positive side of the Z-axis; the front rib plate 41 is located at the edge of the positive side of the bracket main board 11 in the X-axis direction, and the middle part thereof is recessed toward the rear (that is, the middle part of the front rib plate 41 is recessed toward the opposite side of the X-axis, and the two ends of the front rib plate 41 in the positive and negative directions of the Z-axis are arranged close to the positive direction of the X-axis) to form a C-shaped structure, and the rear rib plate 43 is arranged perpendicular to the upper side wall of the seat beam 100 (that is, the side wall on the positive side of the Z-axis).

[0046] In this way, through the C-shaped structural design of the front rib 41 and the design of the rear rib 43 perpendicular to the upper side wall of the seat cross beam 100, the force transmission can be better achieved, and the weight of the bracket main board 11 can be reduced to a certain extent through the middle depression of the C-shaped structure. The front rib 41, the upper rib 42 and the rear rib 43 make the bracket main board 11 have higher structural strength and rigidity.

[0047] When the first rib 3 and the second rib 4 are integrally connected to the bracket main plate 11, the first rib 3 is located at the edge of the bracket main plate 11 opposite the X-axis, and the rear rib 43 of the second rib 4 is also located at the edge of the bracket main plate 11 opposite the X-axis. In this embodiment, by comparison, the first rib 3 is closer to the X-axis, and both the first rib 3 and the rear rib 43 can be made of cast aluminum to achieve an integral connection. In this way, the first rib 3 strengthens the bracket main plate 11 in the Y direction, and the rear rib 43 strengthens the bracket main plate 11 in the Z direction.

[0048] Furthermore, the bracket base plate 12 includes a first base plate 121 and a second base plate 122 that are integrally connected to each other, the first base plate 121 and the second base plate 122 are arranged at a first preset angle, the first base plate 121 is installed on the front side wall of the seat beam 100, and the second base plate 122 is installed on the upper side wall of the seat beam 100.

[0049] Combine Figures 1 to 3 As shown, the first base plate 121 and the second base plate 122 can be made of cast aluminum, and the first base plate 121 and the second base plate 122 are integrally connected through a casting process. A first preset angle θ is formed between the first base plate 121 and the second base plate 122. In this embodiment, θ = 100°~130°. Such a first preset angle θ enables the first base plate 121 and the second base plate 122 to be respectively installed on the front side wall and the upper side wall of the seat cross beam 100 (i.e., the side wall on the positive side of the X-axis and the side wall on the positive side of the Z-axis of the seat cross beam 100).

[0050] In this way, the first preset angle enables the first base plate 121 and the second base plate 122 to be installed on the front side wall and the upper side wall of the seat cross beam 100, respectively, so that the connection stability between the bracket base plate 12 and the seat cross beam 100 is improved, and the integrated design avoids increasing the number of parts, thereby improving the integration level of the pivot bracket.

[0051] Preferably, a first extension rib 411 is provided at the lower end of the front rib plate 41 , and the first extension rib 411 extends to the front side of the first bottom plate 121 , and the first extension rib 411 is integrally connected to the first bottom plate 121 .

[0052] Combine Figures 1 to 3 As shown, a first extension rib 411 is provided at the lower end of the front rib plate 41 . The first extension rib 411 starts from the lower end of the front rib plate 41 and extends along the surface of the first bottom plate 121 . The first bottom plate 121 and the first extension rib 411 are integrally connected.

[0053] In this way, the first base plate 121 is connected to the bracket main plate 11 through the first extension rib 411 and the front rib plate 41, thereby improving the strength of the first base plate 121 and further facilitating the improvement of the structural strength and rigidity of the seat shaft bracket.

[0054] Furthermore, a rotating shaft slot 131 and a first U-shaped hole 132 are provided on the bracket top plate 13. The first U-shaped hole 132 is located on the left and right sides of the rotating shaft slot 131. A second U-shaped hole 21 is provided on the cover plate 2. The rotating shaft slot 131 is engaged with the end of the seat rotating shaft 200. The first U-shaped hole 132 and the second U-shaped hole 21 form a rotating shaft through hole. The seat rotating shaft 200 is rotatably connected to the rotating shaft through hole.

[0055] Combine Figures 1 to 4 As shown, in order to set the shaft slot 131 on the bracket top plate 13, the thickness of the bracket top plate 13 (the dimension along the Y-axis direction) is generally designed to be 24 to 30 mm to ensure that there is enough space on the bracket top plate 13 to open the shaft slot 131. The first U-shaped hole 132 is located on the left and right sides of the shaft slot 131. The end of the seat shaft 200 is placed in the shaft slot 131 to form a snap connection. The seat shaft 200 is placed in the first U-shaped hole 132. A second U-shaped hole 21 is provided on the cover plate 2. When the cover plate 2 is detachably connected to the bracket top plate 13, the first U-shaped hole 132 and the second U-shaped hole 21 are combined to form a shaft through hole, thereby limiting the seat shaft 200 and the seat shaft 200 can rotate in the shaft through hole.

[0056] In this way, a shaft through hole is formed by the first U-shaped hole 132 and the second U-shaped hole 21, so that the seat shaft 200 can be rotatably installed in the shaft through hole, and the shaft clamping groove 131 can realize the clamping and fixing effect with the end of the seat shaft 200.

[0057] Furthermore, first protrusions 133 are provided on the left and right sides of the bracket top plate 13, and the first protrusions 133 extend forward. A receiving groove 130 is formed between the first protrusions 133, and the cover plate 2 is provided with an extension portion 22 and a clamping end 23 connected to the extension portion 22. The extension portion 22 is located in the receiving groove 130, and the clamping end 23 is clamped with the first protrusion 133.

[0058] Combine Figures 1 to 4 As shown, there are two first protrusions 133 on the left and right sides of the bracket top plate 13, and the first protrusions 133 extend in the positive direction of the X-axis to form two hook structures. To ensure the firmness of the first protrusions 133, the thickness of a single first protrusion 133 (the dimension along the Y-axis) is 4 to 8 mm, and a receiving groove 130 is formed between the first protrusions 133. The cover plate 2 is provided with an extension 22 and a snap-on end 23 connected to the extension 22. The extension 22 can be placed in the receiving groove 130, and the dimension of the snap-on end 23 on the Y-axis is larger than the dimension of the receiving groove 130 on the Y-axis, so that the snap-on end 23 is snap-on fixed with the two first protrusions 133.

[0059] In this way, the extending portion 22 is accommodated by the accommodating groove 130 , and the first protrusion 133 extends forward to be clamped and fixed with the clamping end 23 , so that the cover plate 2 can be clamped and installed on the bracket top plate 13 .

[0060] Preferably, the cover plate 2 and the bracket main board 11 are detachably connected via a first connecting member.

[0061] Combine Figures 1 to 4 As shown, the cover plate 2 extends in the opposite direction of the X-axis and in the opposite direction of the Z-axis until it is in contact with the upper rib plate 42. The upper rib plate 42 and the bracket main board 11 are an integrated structure. Therefore, it is equivalent to that the cover plate 2 and the bracket main board 11 are detachably connected together through a first connecting member. In this embodiment, the first connecting member is a bolt, and the cover plate 2 and the upper rib plate 42 are correspondingly provided with mounting holes, so as to perform a detachable connection with threaded fitting.

[0062] The cover plate 2 and the bracket 1 can be fixed only by the above-mentioned snap-fit ​​method, or only by the above-mentioned first connecting member, or by using both snap-fit ​​and the first connecting member connection method, which can better ensure the stability of the connection between the cover plate 2 and the bracket 1.

[0063] Furthermore, the thickness of the first bottom plate 121 is smaller than the thickness of the second bottom plate 122 .

[0064] Combine Figures 1 to 3 As shown, the bracket bottom plate 12 is formed by integrally connecting the first bottom plate 121 and the second bottom plate 122. Figure 3As shown, the plate thickness A1 of the first bottom plate 121 and the plate thickness A2 of the second bottom plate 122 can be intuitively seen, wherein the plate thickness of the first bottom plate 121 is exemplarily designed to be A1 = 5 to 7 mm, and the plate thickness of the second bottom plate 122 is exemplarily designed to be A2 = 8 to 10 mm.

[0065] In this way, by reducing the thickness of the first bottom plate 121, a certain weight reduction effect is achieved, and the thickness of the second bottom plate 122 is greater than the thickness of the first bottom plate 121, so that the structural strength of the second bottom plate 122 is higher, achieving the effect of reducing the weight of components while ensuring structural strength.

[0066] The utility model also provides a vehicle, comprising the seat rotating shaft bracket.

[0067] In the vehicle of the present invention, the seat pivot 200 is connected to the seat cross beam 100 through a seat pivot bracket. The bracket main plate 11 of the bracket 1 is integrally connected to the bracket top plate 13 of the bracket 1, and the bracket main plate 11 is integrally connected to the bracket bottom plate 12 of the bracket 1, so that the bracket bottom plate 12 protrudes from the bracket main plate 11. The cover plate 2 is detachably connected to the bracket top plate 13. The integrated design greatly reduces the number of components of the seat pivot bracket. Multiple components in the traditional technology are integrated into one to form the bracket 1, thereby improving the integration level of the seat pivot bracket and improving production efficiency. In addition, the reduced number of components also reduces the weight of the seat pivot bracket to a certain extent, which is beneficial to controlling the weight of the vehicle. After the bracket bottom plate 12 is installed with the seat cross beam 100, the bracket bottom plate 12 supports and transmits force to the bracket main plate 11 and the bracket top plate 13. The portion of the bracket bottom plate 12 protruding from the bracket main plate 11 provides stability and reinforcement. The seat cross beam 100 and the seat pivot bracket provide relatively stable and reliable support for the seat pivot 200, thereby improving the user experience when the seat back is folded down or raised.
